I have a 20g long tank, and a baby pearlscale goldfish (about 1" long). I got the fish from a friend who was keeping 3 fancies in an uncycled 10 gallon. I'll have to convince her to upgrade or rehome the other two later but that's another story. I've always wanted a big beautiful goldfish so I was happy to take this pretty little one off her hands. This will be my first fish that isn't a betta, and my first attempt at cycling. Will this little fish be okay while I do a fish-in cycle? I can do water checks and changes as frequently as need be (any time the ammonia goes above .25 ppm right?) I have the API master test kit, and Seachem Prime and Stability. I've been researching like crazy and some sources online say that fish-in cycling is inhumane and harmful to the fish. Is that true? Even if I keep the ammonia down and keep the water dosed with prime? I'm going to pop into the local pet store which has a ton of aquarium gear/fish and ask for some cycled filter media. What else can I do? My work schedule allows me to come home in the middle of the day, so I'll be able to test the water multiple times a day and do changes as frequently as needed. I'm already extremely attached to my little fishy and if I can successfully help her grow and thrive I'm hoping it will inspire my friend to take better care of her fish. Help, advice, tips...anything?
